内を示す。(Prior Art) Conventionally, as a device of this type, a technique shown in FIG. 6 described in Japanese Utility Model Application Laid-Open No. 61-71964 is known. In the figure, 2I is a drive unit, 22 is a swinging member that swings in synchronization with the vertical reciprocating movement of a sewing needle (not shown), and 23 is a rotating lever. This rotating lever 23 is rotatable relative to the swinging member 22, and has a looper 2 with an eye hole 24 at its free end.
5 is fixed. Thus, 26 and 27 indicate thread guides, respectively.

記ルーパ２５（目孔２４）を開口を通して露出する仮線
水位置２５゜（２４’）へ移動させていた。Normally, the looper mechanism is covered with an opening/closing body formed on the sewing machine frame, and the threading procedure to the looper (thread guide 2
6, 27, and through the eye hole 24) was very troublesome. Therefore, by rotating the rotating lever 23, the looper 25 (eye hole 24) is moved to the temporary line water position 25° (24') where it is exposed through the opening.
（発明が解決しようとする問題点〉
しかし、上記技術においては、回動レバーを回動して糸
通しを行う際、便宜上、開閉体の開口した両側、即ち、
二方向部から糸の挿通操作が行われていた。この事は手
間を要すと共に、ルーパの糸案内は開閉体の近傍に位置
するため、操作しにくく大変厄介であった。(Problems to be Solved by the Invention) However, in the above technique, when threading is performed by rotating the rotary lever, for convenience, both sides of the opening/closing body, that is,
Thread insertion was performed from two directions. This requires time and effort, and since the thread guide of the looper is located near the opening/closing body, it is difficult to operate and is very troublesome.
また、加えて、ルーパに下糸を挿通するに当り、不用意

である。(Means for Solving the Problems) In order to solve the above problems, the technical means taken in the present invention is to provide a looper stand that is fixed to a drive shaft and swings in synchronization with the vertical movement of the needle. fixing the first and second thread guide members;
A looper having an eye hole and a looper thread guide groove is attached to the looper table so as to be rotatable within a predetermined angle range.
（作用）
ルーパを回動操作すると、該ルーパは第２の糸案内部材
側へ移動する。(Function) When the looper is rotated, the looper moves toward the second thread guide member.
そして、ルーパの目礼が前記第２位と案内部材の糸案内
孔に合致する。Then, the alignment of the looper matches the second position and the thread guide hole of the guide member.
この合致した両孔は、前記第１糸案内部材の案内孔をも
含めて、すべてが開口部の片方側に偏倚し露呈せしめら
れる。All of these matched holes, including the guide hole of the first thread guide member, are biased to one side of the opening and exposed.
（実施例） 第１〜５図に基づき本発明の実施例について説明する。(Example) Embodiments of the present invention will be described based on FIGS. 1 to 5.

ジ６及び７により固定される。In the figure, reference numeral 1 denotes a drive shaft, and a looper stand 2 (fixed by a screw 3) has thread guide holes 4a, 5.
The first and second thread guide members 4 and 5 having a are fixed by screws 6 and 7, respectively.
８はルーパで、目孔９及び糸案内溝１０を有し、カギ孔
１１、長孔１２部分にてガイドピン１３゜１４を介し、
前記ルーパ台２に回動可能に取付けられる。Reference numeral 8 denotes a looper, which has an eye hole 9 and a thread guide groove 10, and is inserted through guide pins 13 and 14 at the key hole 11 and the elongated hole 12.
It is rotatably attached to the looper stand 2.
面シて、１５はバネ部材で、前記ルーパ台２とルーパ８
との間に張架され、この両者間の作動位置を保持する。On the other hand, 15 is a spring member which connects the looper base 2 and the looper 8.
The operating position between the two is maintained.
また、前記第２の糸案内部材５の糸案内孔５ａは、裁縫
状態時には第１図示のようにルーパ８の糸案内溝１０の
左端部に在る。Further, the thread guide hole 5a of the second thread guide member 5 is located at the left end of the thread guide groove 10 of the looper 8 as shown in the first figure during the sewing state.
次いで、本実施例の作用について述べる。Next, the operation of this embodiment will be described.
ルーパへの糸通しに当っては、先ずルーパ８を第１図の
